Studies on Recycled Aggregates-Based Concrete

Recycling has become necessary in the production of concrete, in order to be able to conserve conventional natural aggregate. This article reports on a study of the various physical and mechanical properties of recycled concrete aggregates. The percentages of recycled concrete aggregates were varied. The data showed that some properties, such as compressive strength, showed a decrease of up to 10% as the percentage of recycled concrete aggregates increased. The authors note corrections in water content were necessary to obtain proper workability and to compensate for the higher water absorption of recycled aggregates. For recycled gravel, the values were poor and did not satisfy the minimum standards when the amount of recycled aggregates increased beyond 25%. Fatigue tests showed that specimens made with different types of recycled aggregates would fail after fewer cycles in comparison with specimens made with 100% natural aggregate.
